Fortnite

Resolution Scaling

The measured frame rates for this Fortnite configuration show a clear and consistent scaling pattern as resolution increases across all four settings presets. At Low settings, the average frame rate drops from 435.3 FPS at 1920x1080 to 289.6 FPS at 2560x1440, a reduction of 145.7 FPS, and then further to 151.4 FPS at 3840x2160. This progression demonstrates that the GPU is the primary scaling component at lower graphical loads, as the frame rate responds almost proportionally to the pixel count increase.

Moving to Medium settings, the pattern continues with 325.1 FPS at 1080p, 202.5 FPS at 1440p, and 108.3 FPS at 4K. The transition from 1080p to 1440p costs 122.6 FPS, while the jump to 4K costs another 94.2 FPS. At High settings, the 1080p result of 252.7 FPS drops to 159.1 FPS at 1440p and finally 82.3 FPS at 4K. The Ultra preset shows the most severe scaling, with 165.7 FPS at 1080p falling to 102.8 FPS at 1440p and 55.1 FPS at 4K.

The data suggests that at 1080p and Low settings, the system is likely approaching a CPU or memory bottleneck, as the Intel Core i5-13400F with 10 cores and 16 threads delivers a massive 435.3 FPS — a figure that exceeds what most displays can even present. The 10-core processor, with its 4.60 GHz boost clock, appears sufficient to feed the RTX 5080 at lower resolutions. However, at 4K Ultra, the 55.1 FPS result indicates the GPU is now the limiting factor, as the NVIDIA GeForce RTX 5080 with its 16 GB of GDDR7 memory is being pushed to its limits by the combination of high resolution and maximum settings.

The scaling ratio from 1080p to 4K at Low settings is roughly 2.88x (435.3 divided by 151.4), which is close to the 4x pixel count difference but not fully proportional, indicating some overhead remains. At Ultra settings, the ratio is exactly 3.01x (165.7 divided by 55.1), showing nearly perfect scaling that confirms GPU-bound behavior at the highest preset.

GPU Role

The NVIDIA GeForce RTX 5080 plays a decisive role in these Fortnite results, particularly at higher resolutions and settings. The GPU's 16 GB of GDDR7 memory with a 256-bit bus provides 960.0 GB/s of bandwidth, which becomes increasingly relevant as resolution rises. The memory clock runs at 1875 MHz with 30 Gbps effective speed, supporting the high frame rates observed.

The GPU's boost clock of 2617 MHz and base clock of 2295 MHz, combined with 10752 shading units and 112 ROPs, deliver the raw throughput needed for Fortnite's rendering demands. The 56.28 TFLOPS of FP32 compute power is evident in the 4K Low result of 151.4 FPS, which shows the GPU can maintain high frame rates even at 3840x2160 when graphical effects are minimized.

The RTX 5080's 84 RT cores and 336 tensor cores, while not directly benchmarked in this title's standard rasterization, contribute to the overall architecture. The GPU's 89th percentile ranking among all GPUs places it well above average, and its nearest rivals include the Intel Arc A570M at 1.6% lower average score, the Intel Arc Pro A60 at 1.9% higher, and the Intel Arc A580 at 2.5% lower. These comparisons show the RTX 5080 sits in a competitive position relative to its direct peers.

The VRAM capacity of 16 GB proves sufficient across all tested configurations, as no settings combination appears to exceed available memory. The transition from Medium to High at 4K costs 26.0 FPS (108.3 to 82.3), while the High to Ultra transition costs 27.2 FPS (82.3 to 55.1), suggesting that the GPU's shading units and texture units are the limiting factors rather than memory capacity.

Settings Recommendations

The measured data provides clear guidance on preset selection based on target frame rates. For competitive play where maximum frame rate is paramount, the Low preset at 1920x1080 delivers 435.3 FPS, which exceeds any current display's refresh rate capabilities. Even at 2560x1440, Low settings maintain 289.6 FPS, providing ample headroom for high-refresh monitors.

For players prioritizing visual quality while maintaining smooth gameplay, the High preset at 1920x1080 offers 252.7 FPS, which remains well above the 144 Hz threshold commonly targeted by gamers. At 2560x1440, High settings produce 159.1 FPS, still suitable for most high-refresh displays. The Medium preset provides a balanced alternative, with 325.1 FPS at 1080p and 202.5 FPS at 1440p.

The Ultra preset is only recommended for players with 4K displays who prioritize visual fidelity over frame rate, as it produces 55.1 FPS at 3840x2160 — passable for slower-paced gameplay but potentially insufficient for fast competitive action. At 1440p, Ultra yields 102.8 FPS, which is acceptable but noticeably lower than the 144 FPS target many players prefer. For 4K displays, the High preset at 82.3 FPS represents the best compromise between visual quality and playability, while Medium at 108.3 FPS offers a smoother experience if visual sacrifices are acceptable.

How This Combo Ranks

The Intel Core i5-13400F combined with the NVIDIA GeForce RTX 5080 achieves a combo rank of 68 out of 1564 tested combinations in Fortnite. This places the configuration in the top 4.3% of all tested systems, indicating excellent overall performance for this title. The ranking reflects the synergy between the 10-core, 16-thread CPU and the RTX 5080's substantial graphics horsepower.

The CPU's 82nd percentile ranking among all processors, with an average benchmark score of 25236, positions it closely to several rivals: the Intel Core i7-13620H scores 25201 (0.1% higher), the AMD Ryzen 5 5600X3D scores 25365 (0.5% higher), and the AMD EPYC 9474F scores 25103 (0.5% lower). These narrow margins indicate the i5-13400F provides balanced performance that does not bottleneck the GPU in this title.

The GPU's 89th percentile ranking, with an average score of 59188, shows the RTX 5080 outperforms the majority of graphics cards. Its nearest rivals include the Intel Arc A570M at 58239 (1.6% lower), Intel Arc Pro A60 at 60326 (1.9% higher), and Intel Arc A580 at 57756 (2.5% lower). The combination of a top-quartile CPU with a top-decile GPU yields the strong overall ranking observed.

Measured FPS Breakdown

At 1920x1080, the four settings presets produce the following average frame rates: Low achieves 435.3 FPS, Medium achieves 325.1 FPS, High achieves 252.7 FPS, and Ultra achieves 165.7 FPS. The step from Low to Medium costs 110.2 FPS, Medium to High costs 72.4 FPS, and High to Ultra costs 87.0 FPS. The 1080p results show the largest absolute frame rate differences, as the GPU has the most headroom at this resolution.

At 2560x1440, the results are: Low 289.6 FPS, Medium 202.5 FPS, High 159.1 FPS, and Ultra 102.8 FPS. The transition costs between presets are 87.1 FPS (Low to Medium), 43.4 FPS (Medium to High), and 56.3 FPS (High to Ultra). Compared to 1080p, each preset loses approximately 33% of its frame rate at 1440p, consistent with the increased pixel workload.

At 3840x2160, the average frame rates are: Low 151.4 FPS, Medium 108.3 FPS, High 82.3 FPS, and Ultra 55.1 FPS. The preset transitions cost 43.1 FPS (Low to Medium), 26.0 FPS (Medium to High), and 27.2 FPS (High to Ultra). The 4K results demonstrate that even the RTX 5080 cannot maintain triple-digit frame rates at Ultra settings, but the Low preset remains well above playable thresholds.

The complete dataset shows a consistent pattern: each resolution increase from 1080p to 1440p reduces frame rates by roughly one-third, while the jump to 4K reduces them by another 40-50% depending on the preset. The Ultra preset shows the most uniform scaling across resolutions, while Low settings show the largest absolute frame rate variation.
